Answer:
A) solubility
B)luster
D)Density
F)magnetism
Explanation:
A physical property is one that tells us everything about what a substance is when no change is is occurring to its constituent.
Such properties can be observed with our senses or instruments or pieces of apparatus.
- Examples are luster, density, solubility, taste, odor, color, melting point, boiling point etc.
Answer:
1. provide habitats and shelter for many marine organisms 2. Coral reefs protect coastlines from storms and erosion 3. provide jobs for local communities
Explanation:
Answer:
4.3x10⁻⁵ mol/L.
Explanation:
Hello there!
In this case, since the dissolution of silver phosphate is not completely achieved due to its low solubility in water, we can represent this as an equilibrium problem by which it separates into silver and phosphate ions:
Which are slightly soluble in water; it means that the equilibrium expression is:
Thus, since we know the solubility product and the concentration of these ions in a saturated solution is represented by the reaction extent , we can write:
Thus, solving for we obtain:
Thus, the molar concentration of silver ions is 4.3x10⁻⁵ mol/L.

When thermal energy is added, the motion of particles increases.
This can be thought of when thinking of a gas. We know that a gas includes particles that move fast and are spaced far apart from each other. On the opposite side of the spectrum, we know that a solid includes particles that are closely packed together with limited movement.
Using those examples, we know that a solid usually occurs at colder temperatures (with low thermal energy), and gases occur at warmer temperatures (with high thermal energy).
Therefore, when thermal energy is added, particle motion increases.
